Hi guys, i am moving to a new address that's served by optimum online. For TV, i want to get the cheapest package (just basic channels + their HD counterparts).
The prime mover for flexion of the shoulder muscles used are the following: 1  Pectoralis Major Clavicle. 2  Anterior Deltoid. 3  Biceps Brachii Short Head. 4  Coracobrachialis.
Below the infraspinatus is the teres minor, and below the teres minor is the teres major. Both the teres minor and teres major commence on the shoulder blade and stretch out to the upper arm bone. Together these three muscles assist the latissimus dorsi in shoulders adduction during the pull up. This is the action that moves your upper arm bone into your body, lifting your body up to the bar.
